A nice running FP 25, stock muffler, 10-4 prop, on a profile RST, launch 10,400, wide square wedge 3.5oz tank on uniflow pressure, level flight after bailing out of the overhead 8 the engine runs fine for 7 min, leaning for only the last 3 laps, I kicked the rear of the tank out 3/16 with no change, line tension is fine.
Suggestions?
Chicken Hopper?
